According to
Arstechnica, "Adobe has announced that PDF 1.7 has been approved by the ISO and will become the ISO 32000 standard (DIS)." This information comes from Adobe PDF Architect and a Senior Principal Scientist via his Adobe blog,
Inside PDF where he states that "Adobe has received word that the Ballot for approval of PDF 1.7 to become the ISO 32000 Standard (DIS) has passed by a vote of 13:1."
"... none of the current licensing terms for the PDF standard will change, as it's already licensed for free and readily available to anyone wishing to develop software capable of reading, writing, or processing PDF, but [King] posits that Adobe's Acrobat suite might see an increased level of competition from other companies as a result of the ISO certification."
